I spent a month in Cheeraporn's condo and I found everything I needed to make myself very comfortable. The condo is on the 20th floor and has a beautiful view of the Chao Phraya River and the Bangkok skyline. The condo is facing north with no direct sunlight to heat up the place. It has all everything from a washing machine to a hair dryer. The Wi-Fi is fast and reliable. It has separate aircon units for bedroom and living room and doors can be closed between all rooms so you can quickly cool down a room in an energy efficient way.
Lumpini Place is not the most bustling part of Bangkok in terms of street food, markets, shopping malls, public transportation and so on, but the ground floor has restaurants, a 7-Eleven, hairdresser, dry cleaning and other convenient facilities. There is also a sports club with table tennis and gym facilities and a very nice pool area. Everything is clean and neat. A taxi or motorbike to Sathorn costs around 60-70 THB. However, the bus from Wat Dan BRT costs only 15 TBH and especially during rush hour the bus is a lot faster because it runs in it's own seperate lane most of the way to Sathorn BRT station.
Communication with Ms. Cheeraporn has been prompt and smooth and she helped me arrange transportation from Suvarnabhum Airport to Lumpini Place on my arrival. Both check-in and check-out was very easy. The condo can easily accommodate a couple and is highly recommendable for anyone seeking this kind of place to stay in Bangkok.
